8-3/4 3rd member wanted

[wanderlustin]

Hi all - I'm looking for a 3.55 Sure Grip 489 center section but will entertain a 742.  Would like a drop-in ready diff with no noises and good clutches but will consider rebuildable cores.  Hopefully within driving distance of Vancouver, WA.  Any leads appreciated!  Thanks!!

Did you see the huge pile of 3rd members that Snobar had?   

[wanderlustin]

I didn't!  It certainly falls within driving distance!

Depending on how much you want to spend. Doctor Diff and Mancini racing offer them any way you want it.

I was thinking the same thing.  Used center sections seem to go for nearly what a new diff can be picked up for.  Thanks @Shane Kelley

...at least it seems that way with 3.55 gear sets with the 1-7/8" pinion!

Unless you're into dragging the car more, I don't know if I'd go the 3:55's. Mine has 3:23's and it's turning 3200 rpm at 65 mph roughly and they're not giving the gas away these days. Just my

I go back and forth between 3.23 and 3.55 as my favorite gears. 

What are you running now?  @wanderlustin

How short are your tires? With 3.23 gears, trans in 4th (1to1) 3200 rpm's at 65 MPH means your tire is about 22.5" tall.... Which I seriously doubt so I think your tachometer needs to be calibrated...

With a 27" tire & everything else the same you should be spinning 2650ish RPM's..
